With my eyes.
When flying helicopters we going through a grid square every 50 seconds. I can read ducking 1 over 50k, 1 over a 100k and a 6 minute map.
11b has nothing on a scout pilot when it comes to reading a map.
Wait. I have reading glasses now, so that might slow me down. If only I could find them.
They’re on your head says my wife.
